I took the risk and i did this mod. It worked perfect for me.I connect that red spot to ground. But still, Jonnybravo (or an other electronics engineer) must confirm or else dont try it.
Could you post some pictures of your mod?Quote:

Help with this will be much appreciated.
At 700ohm is the best u can succeed as Jonny mentioned before. Vdroop is not dismissed at all but it wasnt as much as before.
For ground i used the metallic circles around the screw-holes. I dont have pictures of the mod cause i dont have the mobo anymore. It died from humidity after 2 hours dry-ice benching :(
Here is a pic that i found but u cant really see the mod, only the blue trimmer just to believe me :p:

thanks for replying ..=)
By the way how did you manage to find that spot in the first place?
It wasnt my invention :P:
JonnyBravo was the one who found out that the red spot in the pic below should be connected to a resistor in order to decrease vdroop.

The picture is from PWM's datasheet.
But still ....i dont have knowlege in electronics. I just used simple logic. So i wouldnt recommended it to anyone if an expert wont confirm
thanks alot =) i will try and consult a few other specialists about this as well
Yes that is the correct way to do the vdroop mod basically pin 15 to ground. I recommend buzzing out a passive component that is connected to pin 15 in order to avoid damaging the voltage controller and try to keep wire lengths short so a close ground point is ideal.

I avoid using nail polish cause is hard to remove in case of RMA. The problem with IP35 is that the PWM is very very close to socket so u have to be careful. Humidity is high in my place since im just few km from the sea :P
Acetone works GREAT ;)
I have no problems.

@ johnny!
you big geek! :p
ahh you're just jealous :D
who wouldnt be! :D :up: :p:Quote:

You can do this by either having very good eye sight and tracing the copper traces on the board or much easier and safer using a multimeter with a continuity tester that buzzes when there is a short. place one probe on the correct chip pin of the controller and start trying the ends of the SMD capacitors and resistors near that area, when you find one that is connected use it as the soldering point instead.
Hope that helps

Any body know about Vmch mod for this board ?
Johnny Bravo maybe you can help !!!!
bios gives more than enough. P35 can go 550+ fsb with ~1.5v
How about a vDimm mod?
I need to zap my D9GMHs...
both vmch and vddr should be the same as those of the QuadGT, I'll have a look later tonite
For reference:

Thanks Johny I will try later
QuadGT vDIMM mod works on IP35 Pro.
:)
good to hear Largon :up:Quote:
